IODINE STORAGE AND SUPPLY SYSTEM (VERSIONS) AND METHOD OF DETERMINING FLOW RATE AND REMAINING WEIGHT OF IODINE THEREIN Russian patent published in 2019 - IPC F03H1/00 

FIELD: engines and pumps.

SUBSTANCE: proposed group of inventions relates to the field of electric rocket engines (ERE), in particular to the working medium storage and supply systems. Iodine storage and supply system (SSS) (according to the first version) comprises a pipeline communicated with the electric rocket engine with a valve installed on it, a cylindrical vessel with iodine, which is provided on the side opposite to the pipeline, loading flange and piston spring-loaded relative to it, contacting on the other side with crystalline iodine, heaters, one of which is installed in the bottom of cylindrical container, and other – in tubes, hermetically mounted in cylindrical surface of capacity, perpendicular to its axis, as well as receiver, formed by cylindrical reservoir bottom and walls of tubes, includes a bellows installed in cavity between loading flange and piston, wherein one bellows base is tightly connected to loading flange, and the other – with the piston, a potentiometric sensor rigidly fixed to the loading flange, in which the through hole is made, wherein the drive rod of the potentiometric sensor is connected to the piston and installed inside the bellows. In compliance with second version, annular rubber seals are fitted between piston and inner walls of cylindrical container. Also disclosed is a method of determining flow rate and remaining weight of iodine in a storage system.

EFFECT: using the invention enables increasing the speed and reliability of determining iodine consumption by measuring the iodine SSS piston displacement speed, as well as determination of remaining weight of iodine in SSS due to accurate measurement of piston current position.
